Fuel moisture content (FMC) is used in forest fire danger models to characterise the moisture status of the foliage. FMC expresses the amount of water in a leaf relative to the amount of dry matter and differs from measures of leaf water content which express the amount of water in a leaf relative to its area. FMC is related to both leaf water content and leaf dry matter content, and the relati...
in order to evaluate the effects of beneficial free living bacteria (azotobacter chroococcum and azospirillum brasilense) compared to different nitrogen fertilizer levels on yield and yield components of barley (hordeum vulgare cv reyhan) a field experiment was conducted at research station college of agriculture, ferdowsi university of mashhad in 2007-2008. the experiment was arranged in a ran...
In order to evaluate the effects of salicylic acid on some physiological characteristics of common purslane (Portulacea oleracea L.) under NaCl stress, a factorial experiment based on completely randomized design with three replications was conducted in 2013 in research greenhouse of Faculty of Agriculture, University of Yasouj, Iran. Treatments were included of six levels of NaCl salinity (0, ...
Root-knot nematodes cause physiological and anatomical disorders in plants. The present study contains the results of an investigation of the effect of Meloidogyne incognita race2 on the growth of roots and aerial organs of tomato under greenhouse conditions. The experiment in a completely randomized design split split plot on two susceptible (Falat Y) and tolerante (Gina VF) tomatoes variety w...
In order to evaluate the effect of different levels of benzyladenine, nitrogen and salinity on growth characteristics of pistachio seedlings, cv. Badami Zarand, a factorial experiment with three factors: benzyladenine (0, 250 and 500 mg/L), nitrogen (0 and 100 mg N/kg soil as NH4NO3) and salinity (0 and 2000 mg NaCl/kg soil) was carried out as completely randomized design with three replication...
Mycorrhizal fungi symbiosis with plants root through effective uptake of water and nutrients can be reduced the negative effects of salinity. To evaluate the effect of mycorrhizal fungi on some morpho-physiological traits and yield of Summer savory a greenhouse factorial experiment was conducted based on randomized complete block design with three replications at the Laboratory of Medicinal Pla...
abstract this research was conducted to evaluate the effect of gibberellic acid (ga3) (0.250, 500 and750 mg l-1) on vegetative growth of olive sapling (olea europaea l) in 2004-05 at shahid chamran university of ahvaz. the experiment was a completely randomize design with 4 replications. parameters measured were: shoot height, inter-node length, leaf and root area, fresh and dry weight of shoot...
Nowadays, the root characteristics as one of secondary traits along with grain yield are used to response evaluation of rice genotypes under deficit irrigation. Thus, to evaluate the root traits of 40 irrigated rice genotypes to water limited condition a pot experiment was performed in 2014 at Rice Research Institute (Rasht), Iran. Irrigation treatment was applied in two levels include con...
Agrobacterium rhizogenes (pRi), a causative agent of hairy root disease, effectively induces hairy root formation in a variety of plant species. In our study four bacterial strains AR15834, A4, 9435 and C318 and three explants types leaf, stems and roots, were examined. Hairy roots were induced from roots, stems and leaf explants. The highest transformation efficiency of 77% was achieved by usi...
تأثیر مقادیر مختلف نیتروژن بر رشد و بررسی رابطه نیترات دمبرگ و شاخص کلروفیل با نیترات هیپوکتیل تربچه
The aim of this study was measuring nitrate and leaf chlorophyll content in aerial parts of plant, from which we can predict the hypocotyl nitrate content of radish. A factorial experiment in a completely randomized design with five replicates was carried out on two varieties of radish (Cherry Belle and Sparker). Plants were grown in perlite containing pots and were treated with five levels of ...
